Twitch Live Captions — AI Real-Time Subtitles for Streamers

Twitch doesn't offer native live captions for viewers, but millions of people watch streams in environments where sound isn't ideal — loud places, late nights, hearing difficulties, or a different language. Twitch live captions from Live Subtitles add a real-time AI subtitle layer to any stream on your Windows PC, no Twitch Extension needed.

How to enable live captions on Twitch in 3 steps

1. Download Live Subtitles from the Microsoft Store and launch the app.
2. Select "System Audio" as the audio source — captures the stream's audio directly from your speakers.
3. Open any Twitch stream — captions appear in a floating overlay that stays on top of the browser or Twitch app.

Why Twitch viewers need live captions

Twitch streams are live — there's no pause, no transcript, and no rewind for most viewers. For a growing international audience, following a fast-talking streamer with a regional accent can be exhausting. AI live captions convert the streamer's voice to text in under a second, making every word readable.

• Deaf and hard-of-hearing viewers get full access to any Twitch stream.
• Non-native speakers follow language-heavy streams without falling behind.
• Viewers in quiet environments (libraries, offices, late night) use captions instead of audio.
• Language learners watch foreign-language streamers with real-time captions or translation.

Translate Twitch streams into your language

Live Subtitles supports dual subtitle mode: the streamer's speech appears in the original language on the top line, and your chosen translation appears below — both update in real time. This is the closest thing to watching a Twitch stream dubbed into your language, but it works for any streamer, any language, instantly.

Supported language pairs include: English ↔ Spanish, English ↔ Japanese, English ↔ Chinese, English ↔ Korean, English ↔ Russian, English ↔ Portuguese, English ↔ French, English ↔ German, and 40+ more combinations.

Game Mode — captions during fullscreen gaming + streams

Many Twitch viewers watch streams while playing another game — picture-in-picture, second monitor, or background audio. Live Subtitles includes Game Mode (Ctrl+Shift+L) that locks the overlay in a click-through state, so captions stay visible over fullscreen games without interfering with inputs. Switch between watching a stream and playing without losing your captions.

For streamers: caption your own voice

Streamers can also use Live Subtitles for their own benefit during a session:

• Read incoming chat from a language you don't speak — translate messages in real time.
• Follow voice calls with raid guests or co-streamers in other languages.
• Use microphone mode to caption your own speech as a personal prompter.

Note: for adding captions directly into your OBS broadcast output, see the OBS subtitles guide.
